Catalytic Dehalogenation Polymerization of 4,4′-Dihalogentriphenylamines in the Presence of a Nickel Complex

Abstract

Triphenylamine oligomers (OTPAs, n=4-10) were synthesized by dehalogenation polymerization of 4,4′-dihalogentriphenylamines. The OTPAs are a white powder, which is stable on exposure to the air and soluble in benzene, chlorobenzene, chloroform and THF. The OTPAs were characterized by IR, H-NMR and UV-visible spectroscopy measurements. OTPA films prepared by casting from solutions or vapor deposition exhibit a high drift mobility of holes and accordingly double layer organic photoconductors including the OTPA layer show a high electrophotographic sensitivity.
